@dp.message_handler(commands='prof')

Answer 1

Learn the basics of python. That's jokes aside. The difference between global and local variables, as well as the basics of working with classes.
Otherwise, it will be difficult to write any kind of complex bot, and what happens will be hard to maintain and debug.
And specifically on the question: you need to make a query in profil () like SELECT * FROM Users WHERE User_id == message.from_user.id
And yes, you don’t need to form SQL queries through string formatting, this is a good way to shoot yourself in the foot. Read about working with placeholders.
